This compilation focuses chiefly on the impact of afterschool programs on student academic achievement. Although afterschool programs for children have been operating for many years in some communities, the afterschool movement is just a few years old. As public demand for afterschool has grown, so has the demand for accountability. That is particularly true in afterschool programs that spend public dollars. This updated evaluations backgrounder includes new data from ongoing evaluations of LA's BEST and Citizen Schools, as well as recently released evaluations of the YMCA of Greater New York's Virtual Y Program, the Young Scholars Program, Generacion Diez, 21st Century Community Learning Centers throughout Texas and findings from a Yale University study and the Massachusetts After-School Research Study. Highlights from previous evaluations of well known afterschool programs such as The Afterschool Corporation (TASC), Foundations Inc., Project Learn, San Diego's '6 to 6' and more are included. This report is divided into the following sections: (1) The Landscape of Afterschool Evaluations; (2) Summary Lessons from the Data; (3) Afterschool Evaluations in Detail; (4) State-Level Evaluations; and (5) Local or Program Level Evaluations. Also, summaries are provided of several of the most extensive evaluations. Appendix (A) "Afterschool Evaluations at a Glance" provides a summary listing of the studies included in this backgrounder.
